Good Magic is scheduled to ship from Belmont Park to Baltimore on Monday.

Brown said Justify will be a tough horse to beat in the Preakness.

“We’re going to need to improve,” Brown said. “Even though our horse ran an excellent race in the Derby and earned a lot of respect from everybody, he needs to again move forward and we need to have Justify come back to us a little bit. I think that the margin that I saw between the two horses is not out of the question that we’ll be able to make up that difference.”

Bolt d'Oro, Pony Up out of Preakness

Bolt d’Oro, who finished 12th in the Kentucky Derby, will not run in the Preakness, owner/trainer Mick Ruis said Sunday.

Bolt d’Oro has been training at Keeneland since the Kentucky Derby and will target the Met Mile on June 9 at Belmont, the Daily Racing Form reported.

Ruis told the Daily Racing Form he wants to do “the best for Bolt, as much as I would love to run in the Preakness.”

Pony Up, trained by Todd Pletcher, also will bypass the Preakness in favor of the LARC Sir Barton on the Preakness undercard.

Eight horses are now considered likely for the Preakness – Bravazo, Diamond King, Good Magic, Justify, Lone Sailor, Quip, Sporting Chance and Tenfold.

Preakness works

Federico Tesio winner Diamond King breezed five furlongs in 1:01.50 over a sloppy track at Parx Racing in Bensalem, Pa.

“Everything went super, very good,” trainer John Servis said. “It was exactly what I was looking for. I told (jockey Frankie Pennington) I was looking for around 1:01 and then let him gallop out on his own … so it was right on the money.”

Javier Castellano will ride Diamond King in the Preakness.

With trainer Rodolphe Brisset riding, Quip breezed four furlongs in 48.20 seconds at Keeneland. Quip will enter the Preakness off a second-place finish in the Arkansas Derby on April 14.

“He’s shown all the signs that he is back to his own self,” Brisset said. “The race in Arkansas and the trip was pretty hard on him. We gave him an easy week and a half after the Arkansas Derby. We didn’t lose anything because he has been galloping on a daily basis.”

Bravazo, who was sixth in the Kentucky Derby, worked four furlongs in 50.60 seconds at Churchill Downs.
